(EN) A method of affixing a marking to a consumer product (2, 3) of plastics material comprises applying the marking to the underface of a transparent or translucent plastics marker (4) in mirror image. The marker (4) is prefabricated as a member separate from the product (2, 3). Subsequently, the product (2, 3) or part thereof is moulded to the marker so that the marking is readable from the top of the marker (4) through the marker material and through a window (15) formed in the product during moulding. The invention also extends to the marker and to a moulded plastics consumer product provided with the marker.
